Dry Ridge is a home rule-class city[4] in Grant County, Kentucky, in the United States.

From around 1910 to 1960, the city's economy was dominated by business related to its mineral water wells, purported to have healing properties.

[6] Dry Ridge is located north of the center of Grant County.

U.S. Route 25 (Main Street) runs through the center of Dry Ridge, leading north 7 miles (11 km) to Crittenden and south 4 miles (6 km) to the center of Williamstown.

[5] The community now known as Dry Ridge was settled about 1792 as "Campbell's Station" near a spring said to have medicinal qualities.

That same year, a creamery company found mineral water which was believed to have medical properties.

The climate in this area is characterized by hot, humid summers and generally mild to cool winters.
